如何在python3 simplekml中为一个点添加高度？

问题描述

我试图在大约 1000m 处为飞机绘制一个点。文档说我可以在坐标之后添加它，但它不起作用。我正在使用 Jupyter，但这是我的代码。当我在坐标后不添加任何数据时，它会将点放在地面上。当我在坐标后添加高度时，它的作用相同。它似乎没有改变任何东西。

import simplekml
import csv
import pandas

csv_dir = 'C:\Data\Merg_Convert\Output'
csv_in = csv_dir + '\\' + 'Consol.csv'

colnames = ['Time','Freq','ATTN','RSSI','AZ','PlatLat','PlatLon','SourceLat','SourceLon','CellipMaj','CellipMin','CellipTilt','Comments','EndLat','EndLong']
ROUND = 4

data = pandas.read_csv(csv_in,names=colnames)
freqs = data.Freq.tolist()
freqs.pop(0)
[float(i) for i in freqs]
round_ = [round(float(num),ROUND) for num in freqs]
res = [] 
[res.append(x) for x in round_ if x not in res] 
print('Done') #This kicks back a warning but not sure how to stop it. 

def build_kml(freq):
    kml=simplekml.Kml()
    kml_out = csv_dir + '\\KML\\' + str(freq) + '.kml'
    inputfile = csv.reader(open(csv_in,'r'))
    for row in inputfile:
        if row[1] != 'Freq(MHz)':
            rnd_ = round(float(row[1]),ROUND)
            if rnd_ == freq:
                if row[8] != '':
                    kml.newpoint(name=row[1],coords=[(row[8],row[7])])

                pnt = kml.newpoint()
                pnt.coords = [(row[6],row[5],1000.0)] #This is the issue
                pnt.style.iconstyle.icon.href = 'http://maps.google.com/mapfiles/kml/shapes/airports.png'

                ls = kml.newlinestring(name=row[1])
                ls.coords = [(row[6],5000),(row[14],row[13],0)]

                ls.altitudemode = simplekml.AltitudeMode.relativetoground
                ls.style.linestyle.width = 1
                ls.style.linestyle.color = simplekml.Color.blue

    kml.save(kml_out)

for f in res:
    build_kml(f)

这是我的数据示例。

解决方法

我知道这是一个老问题....但以防万一....我认为您需要将高度模式添加到这一点。您只对此处显示的线串进行了操作。 即 pnt.altitudemode = simplekml.AltitudeMode.relativetoground
